A thrust sliding bearing ( 1 ) includes an upper casing ( 3 ) which is made of polyacetal resin and has an annular lower surface ( 2 ); a lower casing ( 5 ) which is made of a reinforced synthetic resin including, in addition to polyacetal resin, reinforcing fibers such as glass fibers contained in this polyacetal resin, is superposed on the upper casing ( 3 ) so as to be rotatable about an axis O of the upper casing ( 3 ) in an R direction, and has an annular upper surface ( 4 ) opposed to the annular lower surface ( 2 ) of the upper casing ( 3 ); an annular thrust sliding bearing piece ( 6 ) which is made of polyacetal resin and is interposed between the annular lower surface ( 2 ) and the annular upper surface ( 4 ); and a tubular radial sliding bearing piece ( 7 ) made of polyacetal resin.
